//flags: -betterC -boundscheck=off struct A{} extern(C): void main() { int* x; x[0 .. 0] = x[0 .. 0]; //OK A* a; a[0 .. 0] = a[0 .. 0]; //Error: TypeInfo cannot be used with -betterC }

Also applies to slice assign with structs. //flags: -betterC extern(C): struct S { int a; } void main() { S[10] array; S val; array[] = val; }

I have a fix for just the slice copy so I'll re-separate the issue of slice assignment.
